Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156918, here are decompositions:

5 + 156913 = 156918
17 + 156901 = 156918
19 + 156899 = 156918
31 + 156887 = 156918
101 + 156817 = 156918
137 + 156781 = 156918
191 + 156727 = 156918
199 + 156719 = 156918

Showing the first eight; more decompositions exist.
